What is Biology A level? Biology is the study of life itself, from the complex interactions of organisms in an ecosystem to the biochemistry of DNA and proteins. Biology is central to many major scientific disciplines such as Biochemistry, Biotechnology and Biophysics. Throughout your studies you will learn the biological basis of issues ranging from HIV to cancer. You will also develop practical and analytical skills and debate the ethical issues that are central to the modern biologist. You should consider biology A level if you are interested in making links between topics you have learnt about at GCSE and if you enjoy reading about scientific developments in the news.
